Flora and Fauna Assessment for Precinct 15, Blackshaws Road, Altona North, Victoria 2 SUMMARY Introduction Ecology and Heritage Partners Pty Ltd was commissioned by Mirvac, on behalf of the Precinct 15 Landowners to update a Flora and Fauna Assessment of Precinct 15, Blackshaws Road, Altona North, Victoria. The assessment was required to inform the Land Use Plan, determine the likely extent of any flora and fauna values within the study area and identify any potential constraints associated with the future development of Precinct 15. Study Area The area known as Precinct 15 (the study area) is located adjacent to the suburb of Altona North, and covers approximately 67 hectares. It is bound by the Westgate Freeway to the north, New Street to the east, Blackshaws Road to the south and Kyle Road to the west. The site is characterised by open cleared land and an old quarry site, with dumped refuse and building material spread throughout the area. It was determined through aerial photography and subsequent ground truthing that approximately half the precinct supported existing developed industrial land, including a disused quarry and some partially demolished buildings. Therefore, the area subject to detailed field assessment was limited to the vacant land within Precinct 15. The remaining land was visually assessed from vacant areas within the precinct, though not subject to a detailed field assessment, as these areas were devoid of any ecological value (i.e. buildings, asphalt car park). Methods A site assessment was undertaken on 4 February, 2010 to obtain information on terrestrial flora and fauna values within the study area. The site was assessed on foot, with all vascular plants recorded and the overall condition of vegetation noted. Habitat features including ground cover composition and structure, and the presence of hollows and fallen ground debris was also recorded. The presence of hollows in isolated trees was noted, and any other features likely to be important for fauna. A site re-visit was undertaken in May 2012, to confirm that flora and fauna values within the study area had not altered considerably from the previous assessment in 2010. Results Flora No indigenous flora species were recorded within the study area during the 2010 assessment. A total of 43 exotic species were recorded during the assessment, including 11 listed noxious weeds. No additional flora species were recorded during the second site assessment in 2012. No significant flora species were recorded during either field assessment, and none are considered likely to occur due to the highly modified condition of the study area. Flora and Fauna Assessment for Precinct 15, Blackshaws Road, Altona North, Victoria 3 Fauna A total of 11 fauna species were recorded within the study area during the 2010 survey, and comprised of two mammals (both introduced) and nine birds (five native and four introduced). Two additional fauna species (locally common native birds) were recorded during the second site assessment in 2012. No fauna species of national, state or regional significance were recorded during either field assessment and none are considered likely to occur, due to the highly modified condition of the study area. Ecological Significance The study area is considered to be of low conservation significance due to the absence of remnant vegetation, the highly modified condition of the site and prevalence of exotic weeds throughout open areas. Legislative and Policy Implications The study area is highly unlikely to impact on any matters of national environmental significance and an Environment Protection and Biodiversity Conservation Act 1999 referral to the Commonwealth Environment Minister is not required. A protected flora licence or permit under FFG Act is not required as the study area does not include public land. A planning permit is not required for the removal of exotic or planted native vegetation. A Permitted Clearing Assessment was not undertaken, as no remnant native vegetation is present within the study area. There are no biodiversity offset requirements for future development of the study area. Conclusion No further flora or fauna surveys are required within the study area due to the highly modified condition of the site and current industrial use. The precinct is surrounded by urban development and is isolated in the context of the local area. In addition, the study area does not support any habitat characteristics for threatened flora and/or fauna species, thus targeted surveys are not warranted prior to future development of the precinct. A Weed Management Plan should be prepared, and incorporated into a Construction Environmental Management Plan to control noxious weeds within the study area during pre-construction and post- construction within the precinct to minimise their spread to surrounding areas and meet requirements under the CaLP Act.
